FINALLY! A drilled washer that actually fits on your radiator mounts. These 22mm OD drilled washers were designed specifically for radiator mount usage. When the current market only offered 18mm washers, which were too small, and 25mm washers, which were too big, we went ahead an made our own. Now you can give your radiator mounts that factory look with our raw 6061 aluminum drilled washers. Designed for use with M6 radiator mount fasteners, these 22mm OD drilled washers offer not only a lighter look, but a lighter weight also, compared to stock washers. They are constructed from 6061 aluminum and are 2mm thick. Also good for front fender mounting and other areas on your bike as well!
